“Techs did a camera inspection on arrival then cleared the line and showed me the before and after video so I knew the problem was handled. They explained options for a longer term trenchless fix in plain terms and never pushed extras.”

4.9Sewage Backup: 85/100
“Our main sewer was backing up repeatedly. Other plumbers kept snaking the line with no permanent results. I Love Sewers came in, ran a proper inspection, and found deep root intrusion. They jetted the line and installed a cleanout so we wouldn't have this issue again. Everything was done under warranty, and I got full documentation with before-and-after video.”

“The house is at least 70 years old and most of the pipes are the original galvanized. We discovered an extremely bad water loss and we put in a call. They found the main issue and then showed us pictures of many more. These guys were incredibly thorough and knowledgeable, being very forthright with sharing that knowledge.”

Common Sewage Backup Scenarios
Stop Using All Water
Every flush and drain use adds to the backup. Stop all water usage in the house immediately until the blockage is cleared.
Avoid Contact
Raw sewage contains bacteria, viruses, and parasites. Don't wade through it or touch it without protective gear. Keep children and pets away.
Ventilate the Area
Open windows and doors near the affected area. Sewage gases (methane, hydrogen sulfide) are hazardous in enclosed spaces.
Call a Plumber Immediately
Sewage backup is a true emergency. Most emergency plumbers can respond within 30-60 minutes. Do NOT attempt to clear a main sewer line yourself.
Frequently Asked Questions
What causes sewage to back up?
Common causes: main sewer line clog (tree roots, grease, debris), collapsed or bellied sewer pipe, city sewer main backup, or heavy rainfall overwhelming combined sewer systems. In Diamond Bar, tree root intrusion is one of the most common causes.
Is sewage backup dangerous?
Yes — raw sewage is a serious health hazard containing bacteria (E. coli, salmonella), viruses, and parasites. Do not touch sewage without protective gear. After cleanup, the area needs professional sanitization to prevent illness and mold.
How much does sewage backup repair cost in Diamond Bar?
Emergency sewer line clearing: $200-$800. If the backup revealed a broken or collapsed sewer line, repair costs $1,500-$10,000+ depending on the method and extent. Professional cleanup and sanitization adds $1,000-$5,000 for significant backups.
Does insurance cover sewage backup in CA?
Standard homeowners insurance in CA typically does NOT cover sewer backup damage. You need a separate sewer backup endorsement ($40-$100/year). If you don't have it, you'll pay for cleanup and repair out of pocket. Check your policy now — before the next incident.
